Consider the investment projects given in the table below. Assume that MARR=10% in the following questions.
n	Net Cash Flow
	Project 1	Project 2	Project 3
0	($1,100)	($1,100)	($1,100)
1	$2,600	$1,990	$1,700
2	($830)	$920	($400)
a) compute i* for each investment, identify all of them
b) compute IRR(true) for the project
c) compute the MIRR at MARR=10%
d) determine the acceptability of each investment
